GASEOUS-FUEL BURNER.

To all 'wliom z't may concern: i

Be it j own-that we, JosErnA. KLonB and RUDOLPH B. KLOEB, citizens ofthe United States, residing at SWayzee, in, the

county of Grant and State of Indiana, have invented cert intnew and useful Improvements in Gaseous-Fuel Burners, of which the following is aispecification y This invention relates to the subject. of

gaseous fuel burners, and more particularly to an improvementin combined generators and burners adapted for general heating purposes.

' One of theobjects of the present invention is to provide a simple,practical,and reliablestructurewhich will effectively convert the liquid fuel into a vapor whereby when the same is mixedgwith air it will form. a highly combustible gas whose flam will assist in continuing the process of vaporization to maintain the operation of the burner aslong as a supply of fuel is availe able.

A further object of the invention is to provide a combined generatorand burner construction wherein the circulation of the gas and gaseous mixture is relatively free or unobstructed, thus-removing to a great extent the possibility of the collection of carbon deposits which vwould hinder the proper operation of the devicei In this connection, it is also proposed to provide a relatively ,capacious mixing tube wherein theliquid vapor and air may be thoroughly mixed in the proper proportions to form the necessary gaseous mixture, and which mixture is highly heated because of the location of the mixing tube of. thedevice over and above the generating retort where it may be bathed in the flame of the burner.

With the above and other'object's in view which will more readilyappear as the na ture of the invention is better understood, the same consists in the novelconstruction combination and arrangement ofparts'hereinafter more fullydescribed, illustrated and claimed. j 1 i i A preferred and practical embodiment of d the invention is shown "in the accompanying lpedfication of Letters Patent. Patented Nov, 19, 1918; Application filed July 1a 1918. Serial No. 245,652.

taken on the line 33 of Fig. ,1 lookingin the direction of the arrows.

Fig. 4 is a side elevation illustrating a modified form of starting pan which also constitutes a flame spreader for directing the burner'fiame in opposite directions;

T'Similar reference characters designate corresponding parts throughout the several figures of the drawings. i

In carrying the present" invention into efiect it is 1proposed to utilize a generating retort Whic is adapted, to' receive theliquid fuel from a suitable source of supply, whereby under the influence, of heat the fuel" will be converted into vapor which when mixed with air may be conveyed to a suitable point with reference. to the retort whereby it may be ignited to thereby provide a flame which willjnot only produce the desired {stove or furnace heat but at the same time maintain the generating action in the retort.

Accordingly,to this end'itis proposed to employ a generator retort designated generally. as l,-the same-preferably being of a circular or ring-like formation and having a central burner opening 2; and also the annular generating chamber 3 adapted to communicate with a source of fuel supply through the pipe 4, and also provided at a point opposite the pipe at with a suitable gas outlet pipe connectionr5. For conveniently supporting the entire, burner device either in the fiI'BrbOX of a. cook stove or fire-potof a heating furnace, the said supply pipe 4: and outlet pipe 5 may have fitted thereto suitablesupporting brackets 6 which may .be adjustably vertically to raise or lower the burner with referenceto the surface to be heated, thus enabling the structure to be suitably adjusted to meet the re quirements of various heating apparatus.

. In connection with the gas outlet pipe 5 which communicates with the generator chamber 3 of theretort, it willbe observed thatthe same projects away from the retort largevolume of gas and air. Furthermore,

' entire tube willlie in close proximity to the upper surface of the retort and receives the fullbenefit of the flame which causes the gene erating action within the retort. And, in. this connection it will be, observed that the intake end of the mixing tube is disposed a sufficient distance beyond th zone of the flame to prevent the igniting of the vapor issuing from the jet orifice 8.

Arranged beneath the retort 1 is a suitable flash pan 11, the same having a swivel connection 12 with the underside of the retort whereby it may be conveniently swung to one side for receiving the priming charge of fuel to start the device, and then swung back into position beneath the retort to give the latter the full benefit of the starting flame when the priming charge is ignited. As shown in Figs. 1 to 3 this flash pan may be of circular formation and will assist in directing the flame issuing from the burner end of the mixing tube through the burner opening 2 upwardly onto the retort and mixing tubeitself. However, when it is desired to use the present device in the fire-box of cook stove, it is desirable to use the type of flame pan 13 shown in Fig. 4 ofthe drawings. This flame pan 13 is of elongated shape and is especially designed to not only direct the flame upwardly onto the generator retort, but also to the underside of the front and rear lids of the stove. I

From the foregoing it will be clear that the liquid fuel, such as kerosene, may be supplied from a suit-abletank, not shown, to the pipe 4 from whence it will make its way into the generating chamber 3 of the retort 1 which has been previously heated by the starting flame in the pan 11,; and after a short period the liquid fuel in the said chamber 3 will be converted into gas and leave the said chamber through the pipe 5 having the lateral jet orifice 8 which'is disposed a short distance from one end thereof and op posite the intake end of the mixing tube 9. In this connection it may be noted that the extremity of the pipe 5 is closed or sealed, and the jet orifice 8 is disposed a' suitable distance back from this closed end, whereby the space between the orifice and said end will constitute a pocket which will serve to trap or collect any relatively heavy particles of foreign matter or carbon which might otherwise obstruct the free discharge of vapor through the jet orifice. After the vapor mixes with the air in the tube 9 the combustible gas. thus formed proceeds through the curved portion of the tube 9 to its outlet end 10 in the central burner opening of the retort 1, where it is ignited by the starting flame and the burning of this gas then takes the place of the initial starting flame to'oontinue the heating of the retort and mixing tube 9, to thereby not only maintain the generating action of the retort and super-heating effect of gases in the mixing tube, but to produce an extremely hot flame which may be utilized for the desired heating purposes. 7 v

Without further description itis thought that thefeatures and advantages of the present invention willbe readily apparent, and it will of course be understood that minor changes in the form, proportion and details of construction may be resorted to without. departing from the spirit of the invention or scope of the appended claims.

We claim:

1. A gaseous fuel burner comprising a circular retort having an annular generator chamber therein and a central burner opening extending theret-hrough, a mixing tube arranged abovethe retort and having one end in communication with the burner opening through the retort, a gas pipe in communication with said chamber and arranged to discharge into one end of the mixing tube, and a flame deflector arranged at the mouth of the burner opening below the retortc i A generating burner device including a a retort having an annular generator chamher and a central burner opening, a mixing tube arranged above the retort and, having its discharge end opening into the central burner opening thereof, and a gas feeding connection between said retort and the intalreend of the mixing tube.

3. A generating burnerdevice including a generator having an annulargenerating chamber and a central burner openings 11 fuel supply connection for said generator. chamber, a mixing tube doubled upon itself and having its discharge end fitting into the upper end. of said burneropening of the retort and also having its intake end disposed beyond the flame zone of the burner, and a gas feeding tube between 1 said generator chamber of the retort and the intake end of the mixing tube,.said gas feeding tube having a jet orifice located back from the closed end thereof.
